Javascript 在两个点中显示数组中的随机字

函数myFunction（）{ var myarray=新数组（“戏剧”、“寓言”、“童话”、“幻想”、“小说”、“民俗”、“历史小说”、“恐怖”、“幽默”、“神秘”、“神话”、“诗歌”、“现实主义小说”、“科幻”、“短篇小说”、“故事”）； var random=myarray[Math.round（Math.random（）*（myarray.length-1））] var display=document.getElementById（“消息”）.innerHTML=random； } 到目前为止，我已经做到了，我正在尝试做的是，单击一个按钮，将数组中的两个随机单词显示在一起。提前感谢您的帮助

id

是唯一的，如果需要在两个位置显示，请使用

class

选择器或添加另一个唯一的

id

，如下所示

<input type="button" id="btnSearch" value="Search" onclick="myFunction();" />
<div id="message">
    <p></p>
</div>
<br>
<div id="message">
    <p></p>
</div>


<script type="text/javascript">
    function myFunction() {
        var myarray= new Array ("Drama", "Fable", "Fairy Tale", "Fantasy", "Fiction", "Folklore", "Historical Fiction", "Horror", "Humor", "Mystery", "Mythology", "Poetry", "Realistic Fiction", "Science Fiction", "Short Story", "Tall Tale");

        var random = myarray[Math.round(Math.random() * (myarray.length - 1))]

        var display = document.getElementById("message").innerHTML=random;
    }
</script>

函数myFunction（）{
var myarray=新数组（“戏剧”、“寓言”、“童话”、“幻想”、“小说”、“民俗”、“历史小说”、“恐怖”、“幽默”、“神秘”、“神话”、“诗歌”、“现实主义小说”、“科幻”、“短篇小说”、“故事”）；
var random=myarray[Math.round（Math.random（）*（myarray.length-1））]
document.getElementById（“message”）.innerHTML=random；
document.getElementById（“message_2”）.innerHTML=random；
}

也许这是一个可行的解决方案

<div id="message">     
</div>
<br>
<div id="message_2">      
</div>

<script type="text/javascript">
    function myFunction() {
    var myarray= new Array ("Drama", "Fable", "Fairy Tale", "Fantasy", "Fiction", "Folklore", "Historical Fiction", "Horror", "Humor", "Mystery", "Mythology", "Poetry", "Realistic Fiction", "Science Fiction", "Short Story", "Tall Tale");

    var random = myarray[Math.round(Math.random() * (myarray.length - 1))]

    document.getElementById("message").innerHTML=random;
    document.getElementById("message_2").innerHTML=random;
    }
</script>

正是我需要的。谢谢不客气，请记住把这个答案标记为正确。

<button type="button" id="myBtn">Search</button>
<div id="message1">
</div>
<br>
<div id="message2">
</div>

document.getElementById("myBtn").addEventListener("click", clickHandler);

function clickHandler(event) {
    event.preventDefault();
    document.getElementById("message1").innerHTML = selectedWord();
    document.getElementById("message2").innerHTML = selectedWord();
}

function selectedWord(){
    var myarray = new Array("Drama", "Fable", "Fairy Tale", "Fantasy", "Fiction", "Folklore", "Historical Fiction", "Horror", "Humor", "Mystery", "Mythology", "Poetry", "Realistic Fiction", "Science Fiction", "Short Story", "Tall Tale");

    return myarray[Math.round(Math.random() * (myarray.length - 1))];
}
